A frequency switchable antenna based on MEMS technology

This work presents a suitable topology of a reconfigurable microstrip patch antenna using RF-MEMS devices. The RF-MEMS devices are activated with a bias voltage applied through RF feeding port. The antenna is designed for switching between two frequency bands of 5.25 GHz and 5.6 GHz. These are the frequency bands of the IEEE 802.11a standard in Europe and in the USA. A good matching is obtained in both configurations. The antenna realized using only two lithographic steps, what significantly reduces production costs. It is important for the fabrication of an integrated antenna system on the chip (SoC).
